SLElGH-COUPLING.

SPECIFICATION forming part of Letters Pa ent No. 367,808, dated August 9,1887. Applies tion filed September 4, 1886. Serial No. 212,666. (No model.)

first, in improved devices for coupling the forward sled to the ends of the bolster, whereby the latter becomes properly supprted,so that lighter frame-work is required for the same, I and thus the appearance of the sled is improved,and yet ample vertical oscillatory play is allowed to the said sled; and the invention further consists in the combination, with the bolster, head-block, and supporting-ring,. of spring-supported bearings interposed'between said parts at opposite sides of the center there of, and conforming to the lateral rocking motion of the sled, all as hereinafter more fully explained, and specifically set forth in the claims.

In the annexed drawings, Figure 1 is a top plan view of the chief portion of a forward bob-sled embodying my improvements. Fig. 2 is a vertical transverse section on line 00 .00,

Fig. 1. Fig. 3 is a vertical longitudinal section on line y 3 Fig. 1. Fig. 4 is an enlarged detached transverse section on line 2 2, Fig. 1; and Fig. 5 is a section on line N N, Fig. 4..

Similar letters of reference indicate corresponding parts.

A A represent the runners of the forward bob-sled.

, B B are the standards, or so-called knees, secured at their feet to the runners in the 40 usual way.

O O arethe crossbeams connecting the knees of one side ofthe sled with those of the opposite side,and r 1' denote the longitudinal bars, or so-ealled raves, which are secured to the 5 top of the crossbeams O O and tie the same to each other.

D represents the bolster mounted on the raves r r, and H H are two cross-bars which are rigidly mounted on a short longitudinal bar, I, and together constitute the head-block,

which is pivoted to the center of the bolster D by a convexed plate, I), on the under side of the bar I, stepped in a recessed plate, d, on top of the bolster D, and the king-bolt e, passing through the bar I, plates 1) d, and bolster D, the body or box of the sled being mounted on top of the cross-bars H H.

In order to bring the bearings of the superincumbent weight nearly or quite directly over the knees B B, and thus relieve the cross beams O C of the-greater portion of the strain, I place the raves r r nearly over the knees B B, and support the bolster D by its ends resting on said raves; and to allow the sled the necessary-vertical oscillatory motion, and at the same time confine the bolster longitudinally in its position,so as to prevent its shifting sidewise on the sled, I employ bearing plates or clipse c, rigidly secured to the end portions of the bolster, and plates a a rigidly attached to the top of the raves r r The bearing-plates a a,I elongate and place lengthwise the raves, so as to brace the latter. The tops of said plates are formed with elongated recesses or sockets f, lying parallel with the bolster D, and at the ends of said sockets are ears 9 g, projecting upward for the plates and perforated for the reception of couplingbolts h h. The clips 0 c, I form each with an elongated eye, t, which is adapted to enter between the ears 99, and is stepped in the socket f, and thus has a rocker-bearing therein, so as to allow the sled to 'freely oscillate vertically. The eye t is perforated to receive through it the coupling-bolt h, by which the bolst-eris securely connected to the sled.

To the under side of the crossbars H H of the head-block is secured the fifth-wheel or supporting-ringR, and, in order to obtain a proper support for the ring on the bolster go without compelling the former to follow the latter in all of its lateral rocking motions, I interpose between said bolster and supporting-ring spring-supported bearings adapted to conform to the lateral rocking motion of the 95 sled. Said bearings I prefer to support by means of a spring-plate, Z, standing with its extremities normally free from the bolster, so as to allow the end portions of the springplate to vibrate vertically.

From the top of each end portion of said plate rise ears n a, between which is pivoted an anti-friction roller, 0, upon which the supporting-ring It rides. In order to relieve the king-bolt from undue strain, I extend a brace, 12, from the lower end of said king'bolt in opposite directions, forward and rearward, and secure the ends of said brace to the end p0rtions of the plate I.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, 1's- 1. The combination, with the bolster, headblock, and supporting-ring, of elastically-supported bearings under said ring, and antifriclion rollers interposed between said bearings and superposed ring, substantial] y as and for the purpose specified.

2. The combination, with the bolster, headbloek, and supporting-ring, of a spring-plate secured to the center portion of the bolster lengthwise thereof, and having its extremities free from the same and supporting the afore said circle, as set forth.

3. The combination, with the bolster, head block, and supporting-ring, of a spring-plate secured to the central portion of the bolster, and having its extremities free from the same, and anti-friction rollers interposed between the free ends of the spring-plate and superposed snpportingring, substantially as described and shown.

In testimony whereof I have hereunto signed my name and affixed my seal, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the Stateof New York, this 31st day of August, 1886.
